Oopl was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is effectively accomplished, the users are unable to get access to them. Oopl ransomware adds its own “.oopl” to all the encrypted files. For example, the file “price_list.xls”, as soon as modified by Oopl, will be titled as “price_list.xls.oopl”. As soon as the encryption is accomplished, Oopl puts its own special text document (_readme.txt) into all the folders that store the encrypted files.
The message mentioned by document requesting the random os extremely comparable to the notifications provided by other ransomware hazards coming from the DJVU family. The caution basically indicates that the files have been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is absolutely true.
The method to encrypt the files utilized by Oopl is not totally investigated. Nevertheless, there is no doubt that each computer owner may be provided a special decryption key, which is absolutely unique. It is incredibly hard to recuperate the information without the appropriate key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Oopl infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have actually launched the Oopl virus into the web. In order to acquire the key and bring back the crucial data, the users are informed to get in touch with the frauds via e-mail or by telegram and to pay the ransom in the amount of $980.
The message likewise states that the people must contact the Oopl authors within 72 hours upon the minute of the information encryption. The alert suggests that by doing so individuals will obtain a 50% discount, for that reason, the ransom amount falls to $490.
